Title:
金属容器のベース
Document Type and Number:
Japanese Patent JP5406183
Kind Code:
B2
Abstract:
An improved metallic can has an integral base that defines a standing ring that is more resistant to buckling than conventional designs. It includes a vertically oriented cylindrical sidewall and a unitary end wall having a recessed central portion and a downwardly flanged rim portion that defines the standing ring. The downwardly flanged rim portion preferably includes a first outer convexly curved annular surface that when viewed in vertical cross-section has a first radius of curvature R1, a second, lower convexly curved annular surface that when viewed in vertical cross-section has a second radius of curvature R2, and a third, inner convexly curved annular surface that when viewed in vertical cross-section has a third radius of curvature R3. Advantageously, the first, second and third radii of curvature R1, R2 and R3 are each different from each other.
